>pwd_

The command pwd(abbreviation of print working directory, it returns the
corrent directory) it is a command, that show the absolute pathname on the corrent directory.
The working directory is the directory where you are standing in. So for
knowing where you are, you can use the pwd command.

cd /home/user
pwd = /home/user

Flags

-P Show the working directory path without symbolic link (links to
folder).
Example: /home/symphoto a symlink to /home/photospwd -P
will display /home/photos.

-L Show the working directory logical path with symbolic link.
Example: /home/symphoto, that redirect to /home/photos,
pwd -L will show /home/symphoto.

Without any flag, -L is assumed, so the normal pwd is in reality pwd -L.
